Tire tread



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the tread pattern repeats circumferentially throughout the outer circumference and shoulder of a tire;

FIG. 2 is a front elevation view thereof;

FIG. 3 is a right side elevation view thereof; and,

FIG. 4 is a left side elevation view thereof.

In the drawings, the dark stippled surface shading represents the recessed groove portions of the tire tread having a depth as best illustrated along the top and bottom edges of FIG. 2. The broken line disclosure of the tire sidewall and inner bead depicts environmental subject matter that forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
